Be it known that I, HENRY A. WISE WOOD,

a `citizen of the .United States, residing at -lowing is aspecification.

The aim of thisin vention is to improve the tra velingcylinderweb-printing press; and to :this end the invention consists of thedevices described and claimed in this specification and illustrated inthe accompanying iive sheets of drawings, in whichy Figure 1 is a planview of a printing-press with my impro vements applied thereto. Fig.

2 is a sectional elevation of the press shown in Fig. -l. Fig. 2u is aview showing a modiiication. Figs. 3 and 4 are diagrammatic viewssimilar to Fig. 2, showing the operating Fig. 5 is a similar sectionalview illustrating a web-perfecting form of tra veling-cylinderprintingpress with my improvements applied thereto. lEig. 6 is a viewsimilar to F ig. 3, illustrating a modification; and Fig. 7 is a diagramillustrating the action of the web when certain of my devices, ashereinafter described, are not used.

The especial aims of my invention are, first, to `provide deviceswhereby the web will be handled more easily in a traveling-cylinder ortraveling-cylinder perfecting-web press, and, second, to provideimproved inking devices.

4In web-printing presses as now organized and used the rapidreciprocation of the cylinder or cylinders causes an air-pressure infront of and asuction behind the moving cylinder. This action isillustrated in Fig. 7, in which an impression-cylinder is shown movingto the right over a stationary bed. In this case the web to the right ofthe cylinder will be bellied in between the guide 17 and the cylinderand will be bellied out between the guides 17 and 18, as shown. The webto the left of the cylinder will be sucked away from the cylinderbetween the guide 16 and the cylinder and will be sucked down betweenthe guides 15 and 16,` as shown. This strain on the web due to theair-pressure and suction caused by the rapid movement of the cylinder,is very objectionable in practice. The reasons for this are that whenthe press Specification of Letters Patent.

is run at a high rate of speed the webis aptto be broken from thiscause, especially if a weak place or splice occurs inthe web, and thatthe tendency of the same is disarrange the register between the -twoimpressions in a web-perfecting press. To remedy these evils, I haverprovided parts which I term wind-shields or guards, which I place insuch relative positions with respect to the exposed portions of the webas to tend to prevent the web being bellied out or pulled in by airpressure or suction.

The second part of my invention consists in a peculiar inking deviceembodying moving ink-distributing tables.

Referring now to theiirst three sheetsof drawings, Ihave showntherein asingle-cylto effect and inder web-printing pressfembodying my-lm-`vrprovements.

Referring to ythe drawings vand in detail, A A represent .the sideframesfof the machine, between which is mountedl or arranged in any ofthe usual mannersthe stationary bed B, upon which the form or formscanbe secured.

lG G represent two reciprocating carriers, which constitute a travelingcarriage. lMounted in this carriage is an impression-cylinder l C,vwhich is adapted to coact with therform or forms on the bed B, so as tomake an impression on either or both its forwardorbackward movements.Onev or more form-rollers F F are mounted in the reciprocating carriageat each side of the impression-cylinder lO, and a distributer E ispreferably arranged to coact with each pair of form-rollers. Asingle-form roller of course could-'be used at each side of theimpression-cylinder. At each end of the stationary bed is mounted aninking device. Each inking device consists, preferably, of fourink-tables L, L', L2, and L3, the ink-tables L and L3 being arrangedstationary in the side frames and the two inkingtables L and L2mechanism whereby they will be laterally reciprocated to nicelydistribute the ink. Arranged .beyond each of these sets of inkingtablesis a fountain I-I, which may be of any of the usual constructions andwhich may haverthe usual spreading or carrying roll h. The carriers G,constituting the reciprocationcarriage, are extended and carry thereinon each side one or more distributer-rollers F2 being arranged andhaving Y roc IOS

F2 F2 F2, as shown in the drawings. As the carriage is reciprocatd thesedistributer or carrier rollers take the ink from the fountain H andspread the same on the inking-tables, where the ink is nicelydistributed by the peculiar action before described, and from theink-tables the ink is taken by the formrollers F F and spread nicely ande venly upon the form or forms. By this mechanism I have provided a verysimple and efficient inking mechanism whereby very delicate and perfectprinting can be done by reason of the large and accurate distribution.

The path of the web and the mechanism d for driving the various partsmay be arranged as follows: The impression-cylinder may carry gearswhich may mesh with stationary racks mounted on the bed in the usualmanner, so that as the cylinder is reciprocated the same will roll toregister with the form or forms. The web may be led from a roll W, whichmay be mounted in any of the usual ways. The web w from the roll isfirst led in between the continuously-running feeding-'in rollers 10,11, and 12 or any of the continudriven by any of the usual thefeeding-in rollers the webis passed around a looping-in roller 13, whichmay be mounted in suitable arms 14 in guides in the side frames. Fromthe feeding-in looper the ,web passes around avstationary guide or rollrollers 20, 21, and 22 or any of the usual continuously-runningfeeding-out devices which may be positively driven by any suitablemechanism not necessary here to describe at length. The arrangement ofthis feeding mechanism is well understood and is so proportioned anddesigned that the web will be held stationary while the cylinder is inimpression and so that the web will be shifted or fed forward while thecylinder is out of impression at either end of the bed, the web beingfed continuously into and out of the press.

The arms 23 and 14, that connect to the loopers, may be connected tocommon arms 24, which may be mounted on a shaft 240 in the main frames Aand A. These arms 24 have studs 25 secured therein, which studs carryrollers 26, which bear on cams 27.

Springs 410 are connected to one end of the arms 24 and stationary partsand serve to keep the rollers 26 on the cams 27.

28 designates a shaft which, if desired, may be the driving-shaft of themachine and which has suitable tight and loose pulleys P and P mountedthereon. Power from the driving-shaft 28 is taken by means of pinions29, mounted thereon, and gears 290, mounted on the cam-shaft 35. f'

3() designates a shaft which is connected to actuate theimpression-cylinder. This shaft is driven from the cam-shaft 35 by meansof bevel-gears 34 and 33 and parallel shaft 320 through the bevel pinionand gear 32 and 31, as indicated. If desired, the shaft 30 may be theshaft to which power is primarily applied, and the driving-shaft 28 maybe arranged so that its pinion will mesh with the gears 290, which arethen placed on the shaft 30, as indicated in dotted lines. This lastconstruction is used where it is desired to reciprocate a` very heavycarriage. On the outside ends of the shaft 30 are mounted cranks 36,which connect by links or pitmen 37 to pivoted levers or arms 38, whichare mounted on a shaft 40, secured in the main frames. These vibratingarms 38 connect by links 39 to the impression-cylinder C or to thecarriers G, whereby the impression-cylinder will be reciprocated overthe form-bed. On the other end of the shaft 320 is mounted a ruiter-gear41, which meshes with a mitergear 42, and turning with the miter-gear 42is a gear 43, which meshes with a gear 44,se cured on a shaft 45.Mounted on this shaft 45 is a boX-cam 46, having a groove 47.

48 designates a pivoted arm or lever which has a roll 49 engaging thegroove 47 of the cam 46, and by this vibrated back and forth.

The tables L and L2, as before described, are mounted in the sideframes, so as to be capable of lateral movement. connects by a link 50and by an adjustable connection 51 to a long rod or link 52, which isused to vibrate the movable inking-tables and which may be also used tooperate the ink-fountains. This arm connects at each end to a lever 53,which has the usual pawland-ratchet connection to the ink-supplyingrolls H of the ink-fountains. The vibrating tables L have short racks54, and the vibrating tables L2 have short racks 55, with which meshtoothed segments 56 and 57, which are mounted on studs depending fromthe stationary tables L. These sectors are given a short vibration bymeans of a short link and connection 58 and 59 to the link 52. By thismechanism as the link 52 reciprocates the inking-rollers of the fountainare turned and the movable ink-tables are reciprocated laterally, sothat the ink will be nicely distributed and spread, as before described.

To prevent the rapid reciprocation of the impression-cylinders frombagging or stretching the web, I provide wind-shields, which arearranged very close to the web. The

IOO

The arm 48 IIO particular wind-shields shown in the drawings areconstructed as follows: A number of rods, as the four rods 60, arecarried across the press between the side frames and carry a thin shieldor guard 61, which is arranged between the guides 15 and 13, as shown,and which may be arranged to bear directly upon or may be arranged at avery slight distance above the web. Between the roll or guide 1.6,carried by the carriage, and the bottoni of the impression-cylinder Iarrange a metallic guard or shield 62, and between the roll or guide 17and the bottom of the impressioncylinder I arrange a similar guard orshield 63. As the cylinder is reciprocated these guards or shields willprevent the web from ballooning or being stretched from the air pressureor suction and are intended to add greatly to the rapid operation of thepress.

The impression-cylinder C has a gap or depression c3, in which may bemounted a set of grippers c2 and a reel c, by which a tympan or blanketc can be tightly stretched around the periphery of theimpression-cylinder. A portion 0f the impression-cylinder is also cutaway, as at c4, on each side of the depression c3. If preferred, the gapor depression may be made larger than shown, thus dispensing with thecut-away portions, which are formed at each side of the depression. Thiscut-away portion of the impression-cylinder cL and the depression c3 areso arranged relatively to the impression peripheral surface of theimpression-cylinder that when the impression-cylinder'is moved so thatthe same is off the form in either direction, as indicated in Figs. 3and 41, the web will not touch the impression surface or cylinder, beingheld therefrom by the lower ends of the wind guards or shields 64 and63. By this means when the shifting of the web around theimpression-cylinder takes place the web will be shifted without rubbingor bearing on the impression-surface and will also be raised away fromthe surface of the ink-tables L3, whereby the web is fed about theimpression-cylinder while the same is over one of the ink-tables and soheld that it will not be blurred or smeared by contact either with theimpression-cylinder or the ink-table.

In Fig. 5 I have shown a sectional elevation embodying a perfecting formof a printing-press arranged to have the improvements before described.In this press an additional bed B and impressioncylinder C are used. Theloopers 13 and 19 are mounted in common arms 130, which may be actuatedby cams in any of the usual manners. The inking apparatus is arranged,as before described, for each bed B and B, and the wind guards orshields are arranged about the web, as described. From the firstiinpression-cylinder the web passes around the stationary guide or roll70, beneath the adjustable register-roll 71, up over the stationaryguide or roll 72, then to the guide or roll 75, carried by the carriage,under the second impression-cylinder C, then around the guide or roll76, also carried by the carriage G, to the feeding-out device. This pathof the web will enable the same to be perfected. If desired, with thismechanism I can arrange a wind guard or shield at the right of the pressbetween the guides or rolls and 72, and the same may consist of a thinmetallic shield or guard 74, carried by the cross-rods 73 73. Theoperation of the parts in the perfecting form of the press issubstantially the same as that in the singlecylinder press, and it isthought that a specific description of the same is not necessary.

In Fig. 6 I have shown a modification of the wind-shield that is used'above the impression-cylinder. The guard instead of consisting of a thinmetallic shield or frame is made .in the form of an endless belt 103,which may be made out of stiff or heavy canvas and which is turnedaround the rolls 100 and 101, mounted in the frames, as shown, and whichhas its ends connected to the carriage, as by rods 104. With thismodification as the cylinder reciprocates the endless. belt will runback and forth and will form a shield, which will prevent the web frombellying or ballooning out by the air pressure or suction.

In some cases instead of arranging the wind-shield above the web toprevent the same from ballooning I may arrange the shield between theweb and the cause of the pressure-that is to say, in the arrangementshown I may arrange the shield below the web,. and such an arrangementis clearly within the scope of my invention. This arrangement is shownin Fig. 2a, the windshields 610 620 being made of sheet metal andsecured in the carriage. The free ends of the same pass over rollers611, so that said shields will reciprocate with the cylinder.

I am aware that many of the details that I have herein described may beapplied by a skilled mechanic to other forms of presses, and theparticular arrangements and relative locations of the cooperatingelements may be greatly varied by a skilled mechanic and stillaccomplish the functions I have described.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-
